I got my HF and dual band VHF/UHF talking watt meters a couple of years ago and I hooked up the HF watt meter TW1 right away and use it a lot but I'd never hooked up the 2 meter and 432 MHz talking meter until today. It works great; just like the HF version. I mentioned the QSY er in the subject line because I finally, after two years of lots of use, had to replace the 9 volt battery.
